To promote the march, event organizers ran a month-long advertising campaign throughout New York City’s subway system. One of the two posters selected from hundreds of entries to represent the campaign depicts the Statue of Liberty submerged up to her armpits in water. Along the horizon, where an ominous ocean meets an overcast sky, big white letters declare: “The Next One Won’t Be Biblical.” The poster is bleak, a clear allusion to the flood in Genesis that only Noah, his family, and several pairs of lucky animals survived, while the unrighteous perished.

“We wanted to make something that was powerful enough and scary enough to get people to look at it,” says Akira Ohiso, who, together with his wife and design partner, Ellie, created the apocalyptic graphic.

“When I share the image on social media, I’ve had cousins of mine who are still quite religious say things like, ‘Oh, please, that’s such hyperbole,'” Ellie says. “And then I’m like, ‘OK, yes, it’s hyperbole. So let’s talk about exactly how high the water has to get on Lady Liberty before you start having a discussion about what’s really happening.'”
